Why Is Thermal Break Aluminum The First Choice Material For Door & Window
Updated: 10 Dec 2024
The market increasingly favors thermal break aluminum doors and windows due to their high strength, excellent thermal insulation performance, good rigidity and fire resistance, large lighting area, corrosion resistance, superior comprehensive performance, long service life, and excellent decorative effect. Nowadays, high-end thermal break aluminum doors and windows have become the first choice for high-end buildings.
Thermal break aluminum cuts off heat conduction by adding insulation strips in the middle of aluminum alloy. This makes transferring heat through the material difficult, improving insulation performance. Therefore, this structure is called "broken bridge insulation aluminum." Usually, broken bridge aluminum doors and windows are composed of two major parts: broken bridge insulation aluminum profiles and hollow glass.
Its working principle is to embed thermal break strips in the middle of the aluminum profile to separate the aluminum to form a "broken bridge," thereby effectively preventing heat conduction. Compared with traditional non-insulated aluminum profiles, the thermal conductivity of thermally broken aluminum profiles is reduced by 40% to 70%. After assembling hollow glass, hardware, screens, glass glue, foam glue and sealing strips on the thermal insulation aluminum profile, the doors and windows are called thermal insulation aluminum alloy doors and windows.
2. Waterproof function of thermal break aluminum: The structural drainage system and drainage outlet are designed with a pressure balance principle, which ensures smooth drainage and good water tightness.
3. Anti-condensation and frost of thermal break aluminum: It adopts three or even up to eight sealing structures to separate the water vapor cavity reasonably, achieve air-water pressure balance, significantly improve water tightness and air tightness, and ensure that the windows are clean and bright.
4. Thermally broken aluminum anti-mosquito screen design: Provide invisible screens that can be installed inside and outside to prevent mosquitoes and flies. These screens are especially suitable for northern areas with more mosquitoes. At the same time, anti-theft screens can be selected to enhance the anti-theft function.
5. Thermally broken aluminum anti-theft and anti-loosening device: equipped with unique multi-point hardware locks to ensure the stability and safety of windows.

Ordinary color aluminum doors and windows do not have insulation strips, cannot achieve thermal insulation and energy saving, and are only sprayed on the surface.
3. Profile wall thickness: The profile section wall thickness of the broken bridge aluminum alloy doors and windows strictly follows the national standard and must be between 1.4 and 2.0mm to ensure the assembly technology and the firmness and safety of the doors and windows. In contrast, the wall thickness of ordinary colored aluminum doors and windows is generally below 1.4mm.
4. Angle assembly process: Broken bridge colored aluminum alloy doors and windows use special angle codes of more than 3mm for angle assembly and use angle assembly glue for sealing. Ordinary doors and windows rely on rivets or screws for connection, which is less firm and safe but low in cost. The assembled broken bridge aluminum doors and windows are sufficient to withstand adults standing and walking. There is a significant gap in technology and quality between special broken bridge aluminum profiles and ordinary aluminum profiles, which cannot be directly compared.
Thermally broken aluminum doors and windows are highly respected for their excellent thermal insulation performance. The unique thermally broken technology and high-quality materials make them outstanding in thermal insulation, energy savings, and environmental protection. As a high-performance choice of door and window materials, broken bridge aluminum has significant competitive advantages in the market and deserves special consideration.
Why is it called "thermal break aluminum"
The "bridge" in "broken bridge insulation aluminum" refers to the "cold and hot bridge" in materials science, and "broken" means cutting off the bridge. Because aluminum alloy has high thermal conductivity, when the temperature difference between indoors and outdoors is large, aluminum alloy will become a "bridge" for heat transfer, resulting in poor insulation effect of doors and windows.Thermal break aluminum cuts off heat conduction by adding insulation strips in the middle of aluminum alloy. This makes transferring heat through the material difficult, improving insulation performance. Therefore, this structure is called "broken bridge insulation aluminum." Usually, broken bridge aluminum doors and windows are composed of two major parts: broken bridge insulation aluminum profiles and hollow glass.
What is the thermal break aluminum profile
The thermal insulation aluminum profile, also known as thermal insulation aluminum or thermal insulation aluminum alloy, refers to an innovative design with aluminum on both sides and thermal insulation treatment through a plastic profile cavity inside. This structure not only combines the advantages of plastic and aluminum alloy but also meets the requirements of decorativeness, strength, and aging resistance of doors and windows.Its working principle is to embed thermal break strips in the middle of the aluminum profile to separate the aluminum to form a "broken bridge," thereby effectively preventing heat conduction. Compared with traditional non-insulated aluminum profiles, the thermal conductivity of thermally broken aluminum profiles is reduced by 40% to 70%. After assembling hollow glass, hardware, screens, glass glue, foam glue and sealing strips on the thermal insulation aluminum profile, the doors and windows are called thermal insulation aluminum alloy doors and windows.
